Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an emergency evacuation system for high-rise buildings, which serves as an evacuation route between buildings in an emergency.

[Prior Art] In recent years, due to the soaring cost of land, buildings are becoming increasingly high-rise. If a fire breaks out in a high-rise building like this, each staircase will become a chimney and flames and smoke will rise upwards with great force, so each staircase should be used as an evacuation route. things become impossible. Therefore, conventionally, in such cases, people on the upper floors of the fire scene have evacuated to the rooftop or escaped through windows on each floor using evacuation ropes, ladders, etc.

[Problem that the invention seeks to solve]

The conventional evacuation equipment and means of evacuation described above have the following problems.

(1) When a fire occurred downstairs as described above, even if an attempt was made to evacuate towards the roof, if the fire force was strong, the stairs would turn into a chimney, blocking the evacuation route to the upper floors.

(2) Next, attempts were made to escape from the windows on each floor using evacuation robes, ladders, etc., but these evacuation tools made it difficult for many people to escape at the same time, so they did not serve as evacuation equipment for everyone.

(3)Also, even if escaping downstairs through a window on the relevant floor was safer than remaining on this floor, if the evacuees were elderly or children, the danger increased and escape was difficult. .

This invention solves the above-mentioned problems of the prior art, and allows a large number of people, regardless of age or gender, to escape easily, quickly and safely at the same time in the direction perpendicular to the flames in the event of a fire, etc. The object of the present invention is to provide an emergency evacuation device for high-rise buildings that serves as a complete evacuation device.

Means for Solving Problem C] In order to solve the above problem, in the present invention, in two buildings facing each other, a hoisting device such as a wire is installed in the building, and the lower end of the wire etc. is fixed to a walkway having a span reaching both openings of the buildings, and the walkway is movably suspended between the buildings to enable passage between the openings of both buildings. shall be. The above-mentioned walkway is of a rotating type, with its tip fixed to the lower end of a wire, etc. of a hoisting machine installed in one building, and rotates around the opening of the other building as a fulcrum. It may be installed in an upright position along the outer wall of one building toward the top, or in an emergency situation, it can be installed across the opening of the other building. In addition, the walkway is
It is a hanging type that is moored to the lower end of the wire of the hoisting operation machine placed opposite each building, and is normally fixed by locking rods installed at the openings of both buildings, allowing for emergency evacuation. It may be provided in an opening of a desired floor so as to be movable by up and down operation.

[Effect]

By adopting the above configuration, in the event that a fire breaks out in either building, the above-mentioned walkway will be spanned between both buildings, allowing emergency personnel to wait and evacuate on the floors surrounding the fire site. A large number of evacuees can be easily, quickly, and safely moved from the building to an adjacent building at the same time.
